Dr Chris Baker is an ecologist who uses DNA sequencing to work out how species interact. His current research uses DNA from blood-feeding leeches to measure animal biodiversity in the Ailao Mountains of China’s Yunnan Province. His previous research took him to the savannas of Kenya where he worked on termites that grow fungus for food, and ants that protect trees from elephants and giraffe.
